This is a educational instructional video on mathematics. This video teaches you to find the reminder in algebraic long division. Let us take an example. Divide xcube+2xsquare-3 by x-2. When you divide you will get xsquare first. You will get xcube-2xsquare. Now subtract this from xcube +2xsquare. You will get 4xsquare. Now you have to divide 4xsquare+0x by x-2. Now you will get 4x. Now you have to subtract 4xsquare-8x from 4xsquare+0x. You will get 8x. Now you have to divide 8x-3 by x-2. You will get 8. Now you have to subtract 8x-16 from 8x-3. Now you will get the reminder as 13.
